Abstract
A conveyor and method for moving articles across a conveying surface using electromagnetically operated movers in a conveyor belt. The movers are retained in tracks in the conveyor belt. A magnetic field source produces a magnetic field that varies across the width of the belt. The magnetic field interacts with electrically conductive material, ferromagnetic material, or permanent magnets in the movers to propel the movers and divert articles engaged by the movers across the belt. Movers with retractable pushers fold down at the sides of the belt to allow articles pushed by other movers to pass over and off the side of the belt.
